Abstract
One of the main questions of frequency hopping (FH) is Frequency-hopping synchronization. In this paper, a TOD (time of day) self-synchronization based method of frequency hopping synchronization is proposed to archive the rapid and reliable synchronization in a high speed hoping system. This method designed a new structure of the synchronization information, which used special rules sending the synchronization information at the transmitter side and applied the slow scanning combined with the maximum likelihood (ML) algorithm to track the FH sequence at the receiver side. We established a simulation platform of frequency-hopping system to simulate the principle and processes of proposed method. The simulation results represented the advantages we archived at the high acquisition probability, the low false alarm rate, and the long synchronization keeping time. And also we discussed the relationship between the transmission BER and the acquisition probability.
